Process and apparatus for the production of paper products

Abstract

A process and apparatus for producing a paper product, in which paper (M) in a particular form, and mixed with water, is subjected to pressure to form a compacted mass which involves, or includes, depositing the mix onto a first conveyor belt ( 10 ) and then progressively forming the conveyor belt into an upwardly open U-shape configuration and compressing the mix by means of a second conveyor belt ( 20 ) guided to progressively enter the first conveyor belt and progressively compact the mix.

1. A process for producing a paper product, in which paper in a particulate form, and mixed with water, is subjected to pressure to form a compacted mass, said process comprising the steps of: depositing the mix onto a first conveyor belt and then progressively forming the conveyor belt into an upwardly open U-shape configuration and compressing the mix using a second conveyor belt guided to progressively enter the first conveyor belt and progressively compact the mix. 
   
   
     2. A process for producing a paper product as claimed in  claim 1 , further comprising the steps of extruding the compacted mass and dehydrating the compacted mass to reduce its moisture content. 
   
   
     3. A process for producing a paper product as claimed in  claim 1 , wherein coal dust is added to the mix. 
   
   
     4. A process for producing a paper product as claimed in  claim 1 , wherein calcium oxide is also added to the mix. 
   
   
     5. An apparatus for producing a paper product, wherein paper in a particulate form and mixed with water is subjected to pressure to form a compacted mass, said apparatus including:
 a first conveyor belt; 
 means for progressively forming the first conveyor belt into an upwardly open U-shaped configuration; and 
 a second conveyor belt with means for progressively guiding the second conveyor belt into the first conveyor belt to progressively compact the mix.
